IMPROVEMENT IN THE MANUFACTURE OF WIRE FASTENINGS FOR JEWELRY.

Specification forming part of Letters Patent No. 217,861, dated July 29,1879; application filed April 21, 1879.

To all whom it may concern:

Be it known that I, WILLIAM W. COVELL, of the city and county ofProvidence, and State of Rhode Island, have invented a new and usefulImprovement in Wire Fasteners for Jewelry; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention has reference to an improved method for securing wires toblanks used to be soldered to jewelry.

The object of this invention is to prepare these blanks and secure thewires without soldering any part thereof, so as to retain the hardness,springiness, polish, and color on the blank as well as the wire, andfurnish the same to jewelers, ready to be secured, at the lowestpossible price.

The invention consists, 'first, in the method of manufacturing wirefastenings for jewelry which consists in stamping indentures and loopsin the strip, inserting the wire through the loops, and securing it inplace; and, second, in improved jewelers stock, consisting of a strip ofmetal colgred and polished on one side, tinned on the other side, andwired, as hereinafter described.

Figure 1 represents an ear-ring wire secured to a blank ready to besecured by ordinary soft solder to an ear-ring. Fig. 2 is a view of partof a strip of blanks stamped to receive the wire. These blanks may beused for earrings, shawl-pins, buttons, and various other pieces ofjewelry to which wires are secured. Fig. 3 is a sectional view throughthe line w or, showing the configuration of the blank when stamped. Fig.4. is a sectional view of the blank, showing the wire secured bypressure,

surplus tin when the same is soldered to the article. This has to beremoved and requires time, while the article itself is injured by themelted tin, which destroys the color and polish.

To avoid all these defects, I first tin one side of a strip or sheet ofmetal uniformly. I now stamp, in suitable dies, the concave indenture a,and at the same time form the loop b. The blank strip consists,therefore, of a number of concave circles or ovals on the tinned side 0,and presents a number of convex circles or ovals, a, with the loop I)and the indenture d, to receive the wire, on the polished side.

6 represents the wire, which is passed under the loop I) and lies in theindentures d d, each forming a semicircular channel, and the whole iscompressed in a suitable-press, by which the loop is embedded in thewire, and the blank and wire are firmly secured together.

As nothing is soldered to the blank, and no heat is used in theconstruction, the sheets or strips can be colored and finished beforesta mping, and they will retain their color and polish; and as theblanks are coated on one side with tin, they can be readily secured tojewelry without the labor, waste, and injury caused by securing theblanks as heretofore constructed.

As only plain sheets of metal and plain wire are used, they can beconstructed at a lower cost than those heretofore made; and as nosoldering is required, all skilled labor is dispensed with, and withproper tools they can be made by cheap and unskilledlabqr.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The improvement in the art of manufacturing wirefastenings for jewelry shown and described, which consists in stampingthe indentures d d and loop b, inserting the wire,

and securing the same, as described.

2. Improved jewelers stock, consisting of a strip of metal colored andpolished on one side, tinned on the other side, and wired, as described.

WILLIAM W. COVELL.
